The radius of person is 1-6mm.
In " convex " the font structure steel, the angle of the 7th fillet and the 8th fillet is 85-90 °, and two
The radius of person is 1-6mm.
The utility model has the advantage of：
1) a kind of Cross section Design of box beam of the present utility model rationally, improves structure integral rigidity, for compression
The enabling capabilities of box beam are also improved；
2) production cost is reduced, the service life of structure is improved；Rate of metal is significantly improved.
